White-Lined Sphinx

Fascinating facts about the White-Lined Sphinx

• Its wingspan of just 2 to 3 inches gives the white-lined sphinx the nickname "hummingbird moth", a reference to its bird-like size and rapid flight. The moth often flies at dusk or dawn, sometimes even in daylight, and is most active at night. While feeding it hovers in front of flowers, steering its position with visual cues from the blossoms, a behaviour that mirrors the hovering of a hummingbird.
• The larvae are powerful eaters that can assemble into massive groupings, stripping whole plants and even covering entire roadways with slick masses as they move. These giant hordes have been observed eating entire host plants and forming huge slick masses that can ruin gardens. Outbreaks in places such as Utah have caused serious damage to crops like grapes and tomatoes, turning cultivated fields into feeding frenzies.
• Native Americans historically collected the caterpillars, skewering and roasting them for feasts and drying any leftovers for later storage. Nutritional analysis shows the larvae contain almost as much fat as hamburger meat, but with roughly one-third less saturated fat. They also provide more calories, protein, carbohydrate, riboflavin and niacin than a comparable serving of hamburger meat, making them a valuable food source.
• Moths of Hyles lineata that possess shorter proboscises tend to pick up pollen on the scales near their eyes, which makes them the most effective pollinators, whereas those with longer tongues usually emerge from flowers without any pollen attached. A 1970s study at Emerald Lake, Colorado recorded this pattern among individuals visiting Aquilegia coerulea flowers.
• All hawk moths, including the white-lined sphinx, possess three colour-sensitive photoreceptors that respond to blue, green and ultraviolet light, giving them acute visual discrimination. Although early work emphasized their reliance on scent, later experiments demonstrated that these moths have excellent vision and can detect subtle light cues from flowers.
